How can I take long-exposure photos normally with my mobile phone during the day?

First switch to the professional mode of the mobile phone camera, also called manual mode, and then adjust the shutter time to become longer

If the mobile phone supports adjusting the aperture, then reduce the aperture

But Because the light is relatively bright in normal daytime

No matter how you adjust the picture, it will eventually be exposed

So you need to add an external light-reducing filter

The function is Reduce the passage of ambient light to obtain a slower shutter time

We can compare the shutter and aperture to a movement of catching water

We regard a correctly exposed photo as just right Filling a bucket of water

The faucet is regarded as the aperture size

The time of filling the water is regarded as the shutter time

We regard normal daytime as normal The size of the water flow

Under normal water flow

Assuming that it takes 1 minute to fill a bucket of water with the faucet fully open

But if we want a long exposure, it means the time to fill the water has to become longer

So we can turn down the faucet, which means the aperture becomes smaller

In this way, the time to fill a bucket of water becomes longer

But because The light in broad daylight is very strong

That is to say, under normal circumstances, the water flow in the water pipe is very large

However, the aperture of mobile phones can be adjusted to a very small value and some cannot be adjusted directly

Also The adjustment range of the faucet switch is very small

So at this time we still want a long water connection time

In the end, it will only cause the water to overflow, which is overexposure

So we have to make the water flow in the water pipe smaller

So we can add some blocking things in the water pipe

Let the water flow in the water pipe become smaller like this Even if you hold water for a long time, it will not overflow quickly

So the light-reducing filter is like this thing that blocks the water pipe

So if you want to take a slow door shot in broad daylight, it means a long exposure

You have to add and subtract light

Otherwise, you will only expose the spots

Stable tripod - control the shutter with headphones - choose the appropriate shooting time - short shutter time - dark glass or plastic cover Mobile phone lens

The operation details are as follows:

1. Don’t overestimate your handheld stability

Generally speaking, a shutter speed of a few tenths is enough to test The stability of hand-holding is great, let alone shooting long exposures of tens of seconds.

Therefore, before taking long-exposure pictures, you should first prepare a tripod, or fix the eight-catch fish bracket somewhere.

Connect the headphones, use the volume keys of the headphones to control the shutter, and try to avoid all factors that can cause jitter.

2. Find good light source conditions

The light during the day is strong. If you shoot according to the exposure conditions at night, the picture will probably be completely white... So even if you shoot during the day , and also be good at finding places with weak light, such as in the shadows, or when the sky is deep blue in the afternoon.

3. Shutter speed selection

Generally, long exposure shooting exceeds 1 second. However, under strong light conditions during the day, the shutter release time should be reduced according to the actual situation to control the amount of light.

4. Block the lens with a cardboard patch

This principle is the same as the neutral density (ND) filter of the camera's light reducer, filtering out the strong light from the outside. The result is a softer and more natural shot.

For mobile phones, you can also use such props to find a piece of dark glass or plastic to block in front of the lens to reduce the impact of a large amount of external light on the picture.

①Prepare a tripod, or something that can fix the phone

②Apple phones need to download a third-party app, and Android phones use the professional mode/manual mode of the camera

Taking the iPhone as an example, we download the slow shutter app (charges apply).

③Fix the phone on the tripod and compose the picture in advance

④Open the app, click the button (red circle) in the lower left corner, and click the light track

respectively You can see 3 shooting modes and 3 parameter settings, sensitivity, shutter speed, and ISO.

It separates sensitivity and ISO here, which actually has no effect. You can just set the sensitivity to "full".

⑤Set the ISO according to the environment you are shooting in. It is recommended to set it below 100. An ISO that is too high will cause an increase in image noise.

⑥Set the shutter speed according to the effect you want to take. The longer the time, the brighter and longer the light track will be.

⑦Start shooting, and after the system shooting is completed, you will get the complete light track photo

Hello, I am very happy to answer your question:

We all guide mobile phones The camera does not have a mechanical aperture or shutter speed (some models do). Even a professional SLR camera needs to use an external accessory ND lens to take long-exposure photos during the day. So for mobile phones, even if you put the ND filter in front of the lens, you can still take slow shutter speed shots, so it is mostly done with the help of software. You can find a lot of slow shutter software in the app store. If you are interested, you can search for it.

In addition, the pictures taken by the dynamic photography in Apple mobile phone can choose long exposure in the effect, which can also have a long effect.

Huawei mobile phones currently have a lot of slow door settings, but the effect is average when used during the day.

The picture was taken by the slow shutter software on my mobile phone, you can refer to the effect

1. Find a good light source. No matter what camera you are using, the first thing you should do is look around to see where the natural light is coming from. It can come from light fixtures, windows, suspended ceilings, or even just direct sunlight.

2. Don’t zoom, the “zoom” of (most) cell phone cameras is not what you might think of as “zoom”. While some phones do have optical zoom, most don't, and any zoom built in is called "digital zoom." In these cases, there's no lens movement inside to adjust the field of view; instead, the only "zooming" is the software cropping the image to a smaller size. You can do this yourself when editing your photos later so you don't lose valuable resolution; you might need it later!

3. Steady Hold Shaky hands are just as bad for mobile images (especially in low light) as they are for larger cameras. When in doubt, take multiple photos or even just one photo. You can use a physical shutter button if you prefer - just press the volume button or even the button on the headphones (or use a Bluetooth shutter release if you prefer) and you'll be a little more stable than lifting your finger to tap the screen

The principle of long exposure is to slow down the closing speed of the aperture to allow more light to enter the CMOS photosensitive component, thereby making the photos clearer. It is mostly used for night scenes, dark light still life, flowing water, etc. theme.

Since the camera needs to continuously obtain light for 1 second or more when making long exposures, the camera must be kept stable during the photo taking process. The long exposure of mobile phones is the same as that of cameras, so if you want to take long exposure photos with your mobile phone, you must first use a tripod to stabilize the body. Since the mobile phone is not designed with a 1/4-inch gimbal interface for tripods, a mobile phone clip is also needed to connect the body and tripod.

If conditions do not allow, you can also use other methods to keep the fuselage stable, such as finding two bricks to clamp the fuselage, or leaning the back of the phone on a fixed object. In short, make sure that the camera body does not shake during the shooting process, otherwise the photos taken will be blurred.

Nowadays, most smartphones have a "professional mode", and most of them can adjust the shutter speed. Usually the exposure time of a night scene with lights is about 1.5 seconds. If there are no lights, you can choose a long exposure of 3 seconds or more. When using long exposure, you should pay attention to adjusting the ISO sensitivity to 100 to avoid overexposing the photo due to automatic exposure.

1. For Apple phones, lower the exposure value of the phone. Click on the screen to see a focus frame. Hold your hand still and slide down. Then open the live broadcast. After shooting, open the photo and slide down. , just select long exposure

2 Android phones generally have a professional mode, slow down the shutter speed and increase the aperture to achieve long exposure

1. Select the professional mode of the phone , or download a professional camera APP.

2. Extend the shutter time.

3 Reduce the aperture and sensitivity to the appropriate position.

4. If the photo is not very good, you can try a few more times.

Most mobile phones have touch focus.

If there is a bright spot in the picture, you can click it to darken it. If the entire picture becomes dark, you can increase it later. brightness.

Change the mobile phone to professional mode. The ISO is the lowest, the shutter is the lowest, and the aperture value is moderate according to the scene!

Or just use streamer shooting on your mobile phone and lower the ISO shutter speed.

I have taken pictures with Huawei Honor before! The effect is okay
